The present invention is directed to isoflavone nanoparticle compositions comprising isoflavone in the form of nanoparticles and preferably a carrier. The isoflavone nanoparticle compositions are particularly useful for preparing cosmetic compositions, pharmaceutical compositions, foodstuff, food and feed additives. In the compositions comprising the isoflavone nanoparticle compositions recrystallization of the isoflavone to bigger particles is retarded.

Isoflavone nanoparticles and use thereof

The present invention is directed to topical compositions, comprising isoflavone nanoparticle compositions. The isoflavone nanoparticle compositions contain isoflavone in the form of nanoparticles and preferably a carrier. In the topical compositions recrystallization of the isoflavone to bigger particles is avoided.
